Lotide

A mini clone of the Lodash library.

Purpose

BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @JayMartensCodes/lotide

Require it:

const _ = require('@JayMartensCodes/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): checks if two arrays are equal
• assertEqual(actual, expected): checks if actual is the same as expected
• countLetters(object1, object2): checks if two objects are equal
• countLetters(string): counts how many letters are in a string
• countOnly(allItems, itemsToCount): counts how many times each item in itemsToCount shows up in allItems
• eqArrays(array1, array2): compares two arrays to see if they are equal
• eqObjects(object1, object2): compares two objects to see if they are equal
• findKey(object, callback): takes an object and a callback function and goes through the object and compares each key to the callback and if the callback returns true it returns the key
• findKeyByValue(object, value): goes through each property of the object and returns the key of the first property to have the value that is passed
• flatten(array): Unnests an array
• head(array): returns the first element of an array
• letterPositions(string): returns an object with the keys being each letter in the string and the values being the indexes at which those letters appear in the string
• map(array, callback): creates a new array based on each element of the inputed array being manipulated by the callback
• middle(array): returns the middle element(s) of an array
• tail(array): returns the last element of an array
• takeUntil(array, callback): creates a new array by looping through all the elements of the given array and pushing them onto the output array until the callback returns false
• without(array, toBeRemoved): returns a new array based on the inputed array but with all elements that match the toBeRemoved paramater removed
